Description
- This application is a continuation-in-part of my co-pending application Ser. No. 09/643,306 filed Aug. 22, 2000 which is hereby incorporated by reference herein as if fully set forth in its entirety.
- This invention relates broadly to the boring of a hole through the wall of a tube from the inside of the tube outwardly at an angle to a longitudinal axis of the tube. More specifically, this invention relates to apparatus for drilling through an oil or gas well casing at an angle to the longitudinal axis of the casing and into the earth strata surrounding the well casing. More particularly, this invention relates to an improved such drilling apparatus and to a means of transporting, deploying and retrieving the drilling apparatus.
- Oil and gas wells are drilled vertically down into the earth strata with the use of rotary drilling equipment. A tube known as a casing is placed down into the well after it is drilled. The casing is usually of made of mild steel and is in the neighborhood of 4.5 inches to 8 inches in external diameter (4 inches in internal diameter and up) and defines the cross-sectional area of the well for transportation of the oil and gas upwardly to the earth surface. However, these vertically extending wells are only useful for removing oil and gas from the terminating downward end of the well. Thus, not all of the oil and gas in the pockets or formations in the surrounding earth strata, at the location of the well depth, can be removed. Therefore, it is necessary to either make additional vertical drillings parallel and close to the first well, which is costly and time consuming, or to provide some means to extend the original well in a radial direction relative to the vertical longitudinal axis of the casing horizontally into the surrounding earth strata.
- The most common means for horizontal extension of the well has been to drill angularly through the well casing at a first 45° angle for a short distance and then to turn the drill and drill at a second 45° angle thereby making a full 90° angular or horizontal cut from the vertically extending well. These horizontal drills have proved useful for extending the well horizontally but have proved to be relatively expensive.
- Another solution to the problem is disclosed in U.S. Pat. Nos. 5,413,184 and 5,853,056, both of which are hereby incorporated by reference herein as if fully set forth in their entirety. In these patents there is disclosed an apparatus comprising an elbow, a flexible shaft or so-called “flex cable” and a ball cutter attached to the end of the flexible shaft. The elbow is positioned in the well casing, and the ball cutter and flexible shaft are passed through the elbow, turning 90°. A motor rotates the flexible shaft to bore a hole in the well casing and surrounding earth strata with the ball cutter. The flexible shaft and ball cutter are then removed and a flexible tube with a nozzle on the end thereof is passed down the well casing, through the elbow and is directed out of the casing through the hole therein. Water pumped through the flexible tube exits the nozzle at high speed and bores further horizontally into the earth strata.
- Prototype testing of the device disclosed in U.S. Pat. Nos. 5,413,184 and 5,853,056 has proven less than satisfactory. In particular, a number of problems plague the device disclosed in U.S. Pat. Nos. 5,413,184 and 5,853,056. For example, the disclosed ball cutter is inefficient at best and ineffective at worst in cutting through the well casing. The inherent spherical geometry of a ball cutter causes it “walk” or “chatter” during rotation as it attempts to bore through the well casing which greatly increases the amount of time required to bore through the casing. Ball cutters are best utilized for deburring, and/or cutting a radius in an existing hole or slot for example and are simply not suitable for drilling holes.
- Another problem is the torsional flexibility of the flexible shaft or flex cable. Rather than transmitting rotational displacement to the ball cutter at 100% efficiency the flex cable tends to “wind up” or exhibit “backlash,” thus reducing the already inefficient cutting efficiency of the ball cutter even more.
- Yet another problem is the tendency of the elbow to back away from the hole in the casing during drilling with the ball cutter. Such backing away causes the elbow outlet to become misaligned with the hole in the casing thereby preventing smooth introduction of the nozzle and flexible tube into the hole in the casing.
- Still another problem is the large amount of torsional friction generated between the elbow passageway and the flex cable which of course increases the horsepower requirements of the motor required to rotate the flex cable. The addition of balls, separated by springs, to the flex cable, in an effort to alleviate the resistance of the apparatus to being rotated, has not remedied this problem.
- A further problem is the closed nature of the apparatus of U.S. Pat. Nos. 5,413,184 and 5,853,056. which prevents its being taken apart, inspected, cleaned and repaired as needed.
- The invention of my application Ser. No. 09/643,306 overcomes the deficiencies of the apparatus disclosed in U.S. Pat. Nos. 5,413,184 and 5,853,056. That invention is apparatus for boring a hole from an inside of a tube outwardly perpendicular to a longitudinal axis of the tube. The apparatus comprises a drill shoe having a longitudinal axis and being positionable in the tube, the shoe having an inlet, an outlet perpendicular to the shoe longitudinal axis and a passageway connecting the inlet and outlet, a torsional load transmitting element having no torsional flexibility in relation to its bending flexibility, having a longitudinal axis and being disposed in the passageway, the torsional load transmitting element being movable relative to itself about first and second perpendicular axes both of which are perpendicular to the longitudinal axis of the torsional load transmitting element, a hole saw connected to one end of the torsional load transmitting element and a motor rotatably connected to the other end of the torsional load transmitting element. Rotation of the torsional load transmitting element by the motor rotates the hole saw to bore through the tube from the inside of the tube outwardly perpendicular to the longitudinal axis of the tube.
- Further improvements in boring technology are nonetheless desired. For example, the invention of U.S. Pat. Nos. 5,413,184 and 5,853,056 is inefficient and time consuming to operate in that after the cutting tool has bored through the well casing the drilling operation must be interrupted so that the entire drilling apparatus can be retrieved to the earth surface in order to remove the well casing cutting tool and to install the earth strata boring water nozzle. The drilling apparatus must then be lowered back down into the well casing to resume the drilling operation.
- The invention includes apparatus for boring a hole from an inside of a casing outwardly at an angle relative to a longitudinal axis of the casing. The apparatus comprises a drill shoe having a longitudinal axis and being positionable in the casing, the shoe having first and second passageways which converge into a third passageway exiting the shoe a torsional load transmitting element and a cutting element connected to one end of the torsional load transmitting element, the torsional load transmitting element and cutting element being positioned in the first passageway during non-use and in the third passageway during use, and a fluid conduit and a nozzle connected to one end of the fluid conduit, the fluid conduit and nozzle being positioned in the second passageway during non-use and in the third passageway during use.
- The third passageway may exit the shoe at any desired angle of between 0° and 90° relative to the longitudinal axis of the drill shoe. The angle may be, for example, 75° or 90°. The apparatus may include an exit insert installable in the shoe to provide variability in the exit angle.
- The torsional load transmitting element has a longitudinal axis, and preferably has no torsional flexibility in relation to its bending flexibility and is movable relative to itself about first and second perpendicular axes both of which are perpendicular to the longitudinal axis of the torsional load transmitting element. The torsional load transmitting element may be freely movable relative to itself about the first and second perpendicular axes.

- Referring first to FIG. 1 a
boring apparatus 10 according to the principles of the present invention is illustrated. Duringuse apparatus 10 is positionable inside a well casing 12 in the earth strata 14 (FIG. 3). Theboring apparatus 10 includes a hollow carbonsteel drill shoe 20.Drill shoe 20 has a longitudinal axis which when inserted intocasing 12, is generally parallel to a longitudinal axis of thewell casing 12.Drill shoe 20 may preferably be fabricated inhalves 20 a, 20 b securable together viabolts 22.Drill shoe 20 may be connected to a ½ inch diameter 6×25IWRC wire rope 24 which is utilized tolower drill shoe 20 down intocasing 12. - A
fluid motor 26 imparts rotation to amotor coupling 28 which is connected to adrill bit shaft 30 itself connected to a plurality of interconnecteduniversal joints 32 which terminate in ahole saw 34 with central pilothole drill bit 36. Abovemotor 26 is amotor locator 38;motor locator 38 anddrill shoe 20 include cooperating structure (not shown; see U.S. patent application Ser. No. 09/643,306 for same) rotatably fixing themotor locator 38 and hence motor 26 relative to theshoe 20 thereby preventing relative rotation betweenmotor 26 andshoe 20 during operation ofmotor 26. -
Shoe 20 further includes afirst passageway 40, asecond passageway 42 and athird passageway 44. Theuniversal joints 32,hole saw 34 anddrill bit 36 reside infirst passageway 40 during nonuse and inthird passageway 44 during use. Similarly, a flexiblefluid conduit 46 with anozzle 48 connected to its end is positioned in thesecond passageway 42 during nonuse and in thethird passageway 44 during use.Motor 26 may be suspended from and supplied with liquid through a ½ inch diameter 0.049 inch wall thickness 316Lstainless steel tubing 50. Similarly,fluid conduit 46 may be suspended from and supplied with liquid through a ⅝ inch diameter 0.049 inch wall thickness 316Lstainless steel tubing 52. -
Third passageway 44 may exit theshoe 20 at any desired angle of between 0° and 90° relative to the longitudinal axis of theshoe 20, depending on the drilling application. Preferably, the angle is in the general range of about 75° to 90°. To provide convenient variability and versatility in the exit angle of thethird passageway 44 one of a number of exit angle inserts 54 may be utilized, each of which inserts would include a different exit angle. For example, two exit inserts 54 may employed, one of which is at 75° (FIG. 4) and the other of Which is at 90° (FIG. 3) thereby providing an operator with a ready means of quickly changing the exit angle depending on drilling conditions etc.Exit insert 54 may be removably installable in theshoe 20 viascrews 56. - Referring to FIGS.1-4,
shoe 20 may include anangled end surface 58 formed as part of anangular locator 60 secured to a lower end ofshoe 20 with abolt 62 and locatingpin 64.Angled end surface 58 is adapted to cooperate with a matinglyangled end surface 66 of a drill shoe depth locator 68 (discussed in more detail below) for locating theshoe 20 at a selected depth in thecasing 12. An angular orientation of theshoe 20 relative to thecasing 12 Is establishable by positioning thedepth locator 68 at an angular orientation relative to thecasing 12. The matingly angled end surfaces 58 and 66 automatically determine the angular orientation of theshoe 20 tolocator 68 and thusshoe 20 tocasing 12. The use thereof will be described below in more detail. - Referring now to FIGS. 3, 5 and6, the drill
shoe depth locator 68 is illustrated which locates thedrill shoe 20 at a selected depth in thecasing 12. Thedepth locator 68 comprises ahousing 70 and may preferably comprise a pair of lockingarms 72 pivotally connected to thehousing 70 as bypivots 74. Thearms 72 are pivotable to and between a retracted non-locking position in the housing (FIG. 5) and an extended locking position wherein at least a portion of thearms 72 project out of thehousing 70 and is adapted to contact the wall of thecasing 12. Anactuator 76 may be included for selectively pivoting thearms 72. Theactuator 76 may comprise a firing mechanism, which fires a charge that propels thearms 72 to the extended locking position, which comprises achamber 78 adapted to accept acharge cartridge 80, agas path 82 between thechamber 78 and each pivotingarm 72 and afiring pin 84 which is selectively activatable to strike thecharge cartridge 80 thus releasing combustion gases which force thearms 72 upwardly into a locking position relative to thecasing 12.Gas vent paths 86 bleed excess gas out ofhousing 70. Preferably thefiring mechanism actuator 76 of thedevice 68 would be activated as thedevice 68 is being lowered into thecasing 12; when thedevice 68 reaches the desired depth as indicated by, for example, a rotary encoder, themechanism 76 is fired propelling thearms 72 upwardly into engagement with thecasing 12, the downward momentum of thedevice 68 further assisting in locking thearms 72 into the wall of thecasing 12. In the alternative, thecharge cartridge 80 andfiring pin 84 could be eliminated; the lockingarms 72 can be forced upwardly into engagement with thecasing 12 by simply loweringlocator 68 at a sufficient velocity such that water in casing 12 moves forcefully upchamber 80 throughpaths 82 and into contact witharms 72 forcing them upwardly. -
Firing pin 84 is spring loaded viacompression spring 85 positioned withinfiring pin housing 87. A firingpin blocking plate 89 normallyblocks firing pin 84 from upward movement. Firingpin blocking plate 89 is maintained in its blocking position via arelease rod 91. Upon upward movement ofrelease rod 91aperture 93 in blockingplate 89 centers around firingpin 84 thereby freeingfiring pin 84 to move upwardly under force ofcompression spinrg 85. - As mentioned briefly above, the
depth locator 68 preferably includes anangled end surface 66 which cooperates with the matinglyangled end surface 58 of thedrill shoe 20. Once thedevice 68 is in position in thecasing 12, a plurality of radially extending horizontal borings can be made into the earth strata by adjusting the angular position of theangular locator 60 relative to theshoe 20, it being contemplated that theshoe 20 andlocator 60 would have a plurality of locatingpins 64 positioned at, for example 5° to 10° increments. Thus, with each 5° or 10° readjustment oflocator 60 relative toshoe 20, theshoe 20 can bore a new radial path radially outwardly from thecasing 12 but at a known increment relative to the previous boring. If desired, theshoe 20 andlocator 60 can be repeatedly readjusted to drill radially outwardly from the well casing 12 in a full 360° circle. - Referring still to FIGS. 5 and 6, there is illustrated a
tool 100 for deploying the drillshoe depth locator 68 in thecasing 12. Thetool 100 comprises ahousing 102 and a pair of lockingarms 104 pivotally connected to thehousing 102 as bypivots 106. The lockingarms 104 are pivotal to and between a retracted non-locking position (FIG. 6) generally within the periphery of thehousing 102 and an extended locking position (FIG. 5) wherein at least a portion of thearms 104 project out of thehousing 102, and are adapted to engage asurface 110 of thedepth locator 68. Anactuator 112 selectively pivots thearms 104 to and between the retracted non-locking position (FIG. 6) and the extended locking position (FIG. 5). The actuator preferably comprises arod 114 which is movable longitudinally relative to thehousing 102 and which cooperates with acam surface 116 on each pivotingarm 104 to thereby move thearms 104. Thus, to lower thedepth locator 68 in thewell casing 12, thetool 100 is engaged with thedepth locator 68 in that therod 114 is in a downwardposition forcing arms 104 outwardly so as to engage underneathsurface 110 of thedevice 68. Once thedepth locator 68 is at the desired depth in thecasing 12, therod 114 is pulled upwardly thereby permitting upward force on thetool 100 to force the pivotingarms 104 inwardly and free ofsurface 110 thus permitting thetool 100 to be withdrawn from thecasing 12. - Referring now to FIGS. 7 and 8 there is illustrated a
tool 200 for retrieving thedepth locator 68 from thecasing 12. Thetool 200 comprises ahousing 202 and a pair of lockingarms 204 pivotally connected to thehousing 202 as bypivots 206. The lockingarms 204 are pivotable to and between a retracted non-locking position (FIG. 7) generally within the periphery of thehousing 202 and an extended locking position (FIG. 8) wherein a portion of thearms 204 project out of thehousing 202 and are adapted to engage the prior mentionedsurface 110 of thedepth locator 68. Aresilient member 210 normally biases the lockingarms 204 to the extended locking position, yet permits upon application of a sufficient force the lockingarms 204 to move to the retracted non-locking position, i.e. during initial insertion ofhousing 202 and lockingarms 204 into depth locator 68 (FIG. 7). - Referring to FIGS. 9 and 10 a
mobile drilling apparatus 300 is illustrated.

mast 308 is preferably mounted to awork platform 340.Work platform 340 is preferably mounted to thetrailer bed 304 for pivoting movement of themast 308 to and between an upright operable position and a lowered inoperable position, and is also mounted to thetrailer bed 304 for movement transverse to a longitudinal axis of thetrailer bed 304 thereby providing transverse alignment ofdrill shoe 20 tocasing 12.Hydraulic cylinder 342 may be operable between thetrailer bed 304 andmast 308 to pivot themast 308 relative to thebed 304.Hydraulic cylinder 344 may be operable between thework platform 340 andtrailer bed 304 to move thework platform 340 transversely to the longitudinal axis of thetrailer bed 304. -
Trailer 302 may additionally comprise acatwalk 350 extending along thetrailer 302 on one side thereof and mounted to thetrailer bed 304 for pivoting movement to and between an upright inoperable position and a lowered operable position wherein thecatwalk 350 extends the width of the trailer bed. Ahydraulic cylinder 352 may be operable between thebed 304 andcatwalk 350 to pivot thecatwalk 350 and between the upright inoperable and lowered operable positions.Catwalk 350 may include a set ofsteps 354 secured thereto such that when thecatwalk 350 is in the lowered position an operator may climb the steps from a ground surface to thetrailer bed 304. - With reference to FIG. 10 the apparatus may further preferably comprise
